M'ECHANICA'L NIOVEMENT FOR DOUGIf-HANDLING MACHINES.

Patented July 22, 1919.

Application filed November 6, 1918. Serial No. 261,321.

To all mm it may concern: Be itvknown that I, B YAN D. PINKNEY, a

citizen of the United, States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have-invented a new and useful Mechanical Movement for Dough-Handling Machines, of which the following is a specification. g, V I w 7 My invention relates to that type of mechanical movements which are applicable to dough-handling machines'such as disclosed in Patent Nos. 986,413 and 993,138; and its object is to provide mechanical movement for imparting a plurality of oscillations or punches to one rotation of a punching disk'or member which handles or rounds u the'dough that is simple, positive, and efli cienth I V VI attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a plan view of my mechanical movement; Fig. 2, a vertical transverse sec-- tion.

rigidly secured to the frame by any suitable means; 3 is a punching disk in which I have shown the movable or eccentric gear 3* of my mechanical movement as being integral, though said gear may be separate and fastened to said punching disk 3.

Essentially, my mechanical movement comprises the rotary member 7 in which is rigidly mounted the drive shaft 8, a stationary or concentric gear 1 (which I have shown as being integral with the frame 1, though said gear may be separate and bolted or otherwise fastened to said frame) with a mating pinion 4, a movable or eccentric gear 3 with a mating pinion 5, a shaft 6 to which said pinions 4 and 5 are rigidly secured, and a crank-stud 9, which, as drive shaft 8 rotates, imparts the oscillations to the punching disk 3. I have shown a collar 10 to prevent the punching disk 3 from vertical dislodgment. A collar 17 is secured to the drive shaft 8to hold said drive shaft and co-acting parts in proper alinement. As rotary member 7 rotates the pinion 4 is caused to rotate due to the intermeshing with the stationary or concentric gear 1. In turn pinion 5 is caused to rotate, since the pinions 4 and 5 are rigidly secured to the Referring to the drawing, 1 is the frame of amachlne 1n whlch I have shown my mechamcal movement incorporated; 2 1s pan H shaft 6 and hence integral,and as said pinionintermeshes with the movable or eccentric gear3 there is a similar rotarymovement imparted to said movable gear, the difference in their relative velocities being con trolled by the gear ratios of the gear trains. If the ratios of the-train 4 and 1 and the train 5 and3 are identical there will be no actual rotary motion imparted to the disk 3, but merely an oscillatory movement due to the eccentricity of the shaft 9. The action of the stationary gearmovement (pinion 4 rotating and revolving around the gear 1 and the reaction of the movable gear-movement (pinion '5 rotating and revolving around the gear3 in case of equal ratios, equalize each other. In practiceit is desirable tohave the disk 3 make about sixteen complete oscillations or punches for each one rotation. -This punching action is necessary to punch the dough, and the rotary movement necessary to give the dough the rounding efi'ectand cause the dough to travel around the pan 2. The direction of rotation of the disk 3 is shown by an arrow. a

For an example, in the drawing the stationary gear-ratio is 112:28 (112 teeth in the gear 1 and 28 teeth in the pinion 4) and the movable gear-ratio is 128:30 (128 teeth in the gear 3 and 30 teeth in the pinion 5). Since 112:28 is the same ratio as 120:30, the differences between the gear 4 .1. The excess in the ratio is 8 in 128, or onesixteenth; hence, the disk 3 makes but onesixteenth the number of rotations as does shaft 8. Any desired variations of speed may be obtained to suit specific needs. As will be manifest from a study of the mechanical movement the number of rotations of disk 3 is dependent upon the difference in the gear ratios of the lower gears (4 and 1) and the upper gears (5 and 3 In operation the disk 3 of the doughhandling machine in which my mechanical ratios in the example are 4:1 and 4 movement is shown incorporated is carried tuckers 16 in, thevpath of the dbugh. These tuckers are secured to the pan 2, and were 7 the subject of Patent No. l,087,56 l. The

dough to be handled or roundedup'is"deposited in the pocket 2 To operate the dough-handling machine and 1, and pulley shaft 13 is shown journaled in bearings 1' and l.

Other modes of applying the principle of my 'invention may be employed instead of the one explained, provided the means stated by any of the following claims or the equivalent of such stated ployed.

Having-thus described my invention, what I claim as new, and desire to secure by Letters Patent, is V p 1. A mechanical movement of the character described wherein revoluble and'rotary movements are'simultaneous'ly imparted to a unching disk, comprising a punching disk, crank-pins means for revolving said punching disk, and multiple sets of mating gears of different gear ratios for simultaneously impartingrotary movement to said punching disk.
